Abstract :
Polystyrene based scintillator SCSN38, wavelength shifter Y7 with polymethylmethacrylate matrix and pure PMMA light guide GS218 have been irradiated in the mixed field of a pool reactor. About 74% of the released dose was caused by the γ field, 26% by fast neutrons (SCSN38). The total dose ranged from 1.7 to 91 kGy. The measurements were made using alanine dosimeters. Transmission and fluorescence of the samples has been measured before and several times after irradiation, The results show no differences to former irradiations in pure γ fields
